A random tail pulse generator is presented in which the mean rate is adjustable from 10 Hz-1 MHz in decade steps with continuous adjustment within each decade. The time interval distribution is verified to be Poissonian. Minimum spacing between adjacent tail pulses can be smaller than 100 ns. Rise time can be set from 25-1000 ns in six steps. The decay time constant is also adjustable in the range of 10-1000 μs. Double tail pulses can be produced by using a mixed triggering facility which is described. Spacing between these two pulses is continuously variable from 0.1-100 μs. The generator can have the average random rate controlled by a periodic source.
